Samsung NX 20-50mm F3.5-5.6 ED: 18 facts and highlights

1. widest aperture at maximum focal length

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

2. Has full-time manual focus

With full-time manual focus you can move the focus ring whilst it is in AF (auto focus) mode. This means that you can make manual adjustments once the AF has finished, without changing to manual mode.

3. Front element doesn't rotate

The front element doesn’t rotate. This is important if you use filters, as some such as polarising or gradient filters have to be orientated a certain way.

4. minimum focus distance

This is the closest distance that the lens can focus. A shorter minimum focus distance allows you to get closer to your subject, and is particularly important when doing macro photography.

5. maximum focal length

A longer maximum focal length allows you to focus in on a small part of a scene, and offers a narrower angle of view than shorter focal lengths.

6. minimum focal length

A shorter minimum focal length allows you to get more of the scene in the photo, and offers a wider angle of view than longer focal lengths.

7. smallest aperture at maximum focal length

A smaller aperture reduces the amount of light reaching the sensor. This is important in bright conditions where a wider aperture could result in your image being overexposed. Another advantage is that with a smaller aperture you get a greater depth of field, and can keep all of the image in focus.

9. Has focus motor

Lenses with a built-in focus motor can autofocus even if the camera does not have its own focus motor.

10. widest aperture

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

11. Has rounded aperture blades

Similar to the number of aperture blades, rounded blades affect the way the light gets through to the sensor. Rounded blades, often only found on more expensive lenses, improve the appearance of the out-of-focus areas. This allows you to attain better, softer looking bokeh in your photos.

12. magnification

A true macro lens has a magnification of 1:1. This means that the image produced is a life-size representation of the subject being photographed.

13. optical zoom

The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.

14. aperture blades

The aperture controls how much light gets through to the camera’s sensor. More blades is often an indicator of a better quality lens. It also allows you to achieve much nicer looking bokeh when blurring out your background, whereas a lens with less blades will often produce harsher, more polygonal bokeh.

16. minimum angle of view

At the longest end of the lens you get the narrowest angle of view. This allows you to fit a small portion of the scene into the photograph, such as when you are zooming in on a subject (based on APS-C format).

17. maximum angle of view

At the shorter end of the lens you get the widest angle of view. This allows you to fit more of the scene into the photograph (based on APS-C format).

18. Is a normal lens

A normal lens is one that doesn't fall into another category such as wide angle or telephoto, and typically has a focal length between 35mm and 70mm. These lenses aren't tailored towards a specific type of photography, and so are quite versatile.
